What a great show this is! Thankfully, more episodes appear to be on the way. More information can be found in
this dedicated thread about it. This is the pilot episode that was on a couple of years ago and is now back on Channel 4's streaming service again. I think they've released it ahead of upcoming new episodes.
Basically two couples are stripped completely naked and have to make their way off a big hill in the wilderness to a town called Skipton. Laura is really hot and the interactions between the naked couples and members of the public are brilliant. Very brave to do this, so hope you enjoy. It's completely uncensored, apart from the brief intro at the beginning for some reason which blurs their lower parts. Looking forward to more episodes becoming available soon!
